High performance rubidium atomic clock

Product Introduction

   The LX-B21 rubidium atomic clock is a small, high-performance rubidium atomic clock. It uses the "0-0" ultra-fine energy level transition frequency signal of the rubidium atom to lock the voltage-controlled quartz crystal oscillator and output an accurate and stable 10MHz standard frequency signal and 1PPS pulse signal. The LX-B21 rubidium clock uses a quantum physics system with completely independent intellectual property rights, and the unique domestic alkali-free glass reduces the frequency drift of the rubidium clock. The LX-B21 rubidium clock is manufactured with domestic components and can work in dynamic and harsh environments such as vehicles, and can receive reference 1PPS signals for taming.
